Abstract: 1,071,548. Centrifugal pumps. DRYSDALE & CO. Ltd. June 13, 1966 [June 12, 1965], No. 24920/65. Heading F1C. In an electric motor-pump unit, the assembly of motor 8, Fig. 2, an end cover 4 for the pump casing 1 and the pump impeller 10, is hinged at 5 to the casing to facilitate access to the pump. The assembly can be rotated anticlockwise to the position shown by a detachable handle 23 after disengaging locking screws (27), Figs. 1 and 4 (not shown). A pin 21 in one of a number of transverse holes through a pivoted rod 18 prevents further anticlockwise rotation of the assembly due to gravity. The rod 18 may be replaced by a flexible stay, e.g. a wire rope. In an alternative embodiment, Fig. 3 (not shown), the rod is threaded and passes through a pivoted nut (15) carried by the end cover, rotation of the assembly being effected by turning the threaded rod relative to the nut by means of a key located over the free end of the rod. An O-ring seal (11) is located between the casing and end cover. To provide for impellers having larger axial widths, a spacer ring (24) and a further O-ring seal (25) are placed between the casing and end cover, the position of the hole for the pin of hinge 5 being adjusted accordingly.

Abstract: 1,134,383. Cement composition. PROGIL. 31 May, 1967 [1 June, 1966], No. 25039/67. Heading C1H. [Also in Division C3] A composition comprises an intimate mixture of an hydraulic binder and a polymer of formaldehyde and an acrylamide, preferably in amount 3-10% by wt. The hydraulic binder is preferably a quick-setting cement. The composition may also include a filler, such as sand, gravel or clay, and a cement-setting regulator, e.g. CaS0 4 . Polymerization may be carried out in situ, i.e. by mixing the cement, an aqueous solution of formaldehyde and an acrylamide monomer, or a pre-polymer thereof, a polymerization catalyst and optionally the filler and allowing the mixture to set. A preferred process comprises mixing together a dry component comprising the cement, the filler, the cement-setting regulator and part or all of the polymerization catalyst, and liquid component comprising the aqueous solution of the monomers and optionally part of the catalyst. The aqueous monomer solution may have a solids content of 30-60% by wt. and the molar ratio of formaldehyde : acrylamide may be 0À5 : 1 to 1À5 :1. Polymerization catalysts include organic peroxides such as benzoyl peroxide, per-salts such as potassium persulphate or Redox systems (e.g. chloric acidalkali bisulphite) to which organic or inorganic acids or alkaline reagents such as water-soluble hydroxides or carbonates have optionally been added. The preferred catalyst is a mixture of ammonium or alkali metal persulphate and a liquid dialkylaminopropionitrile.

Title: Improvements in or relating to carburettors
IPC: F02M7/17
Filed: 1935-09-09
Abstract: 462,333. Spray carburetters. GRACE, C. J. Sept. 9, 1935, No. 25096. [Class 7 (iii)] A carburetter comprises an air-inlet valve adapted to be opened by engine suction and mechanically linked to a control for a fuel orifice, or orifices, to open or close it in correspondence with the air inlet valve, and a manually controlled fuel valve in the channel leading to the controlled fuel orifice, which limits the rate of feed of the fuel and accordingly serves as speed and power control device for the carburetter. As applied to a downdraught carburetter, fuel flow from a float chamber 1 is controlled first by a manually operated needle valve 7 before the fuel reaches a passage 8 leading to a second fuel valve 16 mounted on a piston 11 operating in a chamber 13 open to engine suction through a conduit 14. The conduit 14 opens adjacent a constriction in the mixing chamber, formed by a bullet-shaped air inlet valve integral with the piston 11, the suction thus controlling the fuel supply within the limit imposed by the valve 7. Fuel is sprayed from slots 19 between an annulus 18 and a lip on the wall of the mixing chamber opposite the base of the tapered nose of the air inlet valve. When used with a floatless carburetter, fuel is supplied under pressure and a byepass prevents a predetermined maximum pressure from being exceeded. Specification 392,929 is referred to.

Title: Improvements in methods and means for forming joints between thermoplastic sheets
Inventor: PICKERING JOSEPH
IPC: B26D1/04
Filed: 1950-10-16
Abstract: 709,907. Making bags. CASCELLOID, Ltd. Oct. 1, 1951 [Oct. 16, 1950], No. 25157/50. Class 94 (2) [Also in Group VIII] Bags are made from a length of flattened tubular thermoplastic material such as polyethylene by intermittently advancing a continuous length A of such material and clamping it between a pair of jaws 20, 21 in the rest periods, severing the clamped material transversely to its length at a distance from the bite of the jaws to cut off a bag at the tearing end of the material A, applying heat to the exposed end of the parent stock thereby produced to cause the material to melt and coalesce, and unclamping and re-advancing the stock for repetition of the clamping, severing and heatsealing cycle. As shown, the tubing A is fed forward intermittently by rollers 9, 10. While the tubing is stationary, rotation of a cam shaft 29 causes (a) upper jaw 20 to descend and clamp the tubing against fixed lower jaw 21, (b) an arm 46 to swing down about a pivot 47 whereby an anvil plate 52 is swung up against jaw 21 and a knife 49 descends alongside plate 52 to sever the tubing, (c) arm 46 to swing up again whereby knife 49 and plate 52 are retracted to leave the severed tubing projecting slightly beyond the bite of jaws 20, 21 and (d) a gas burner 54 carried by an endless chain 62 to be traversed across the width of the jaws whereby the projecting tube material melts and coalesces and, on cooling, forms a seam. Stationary cam sur.- faces at the ends of the burner's travel cause the latter to be swung to a vertical position for the inoperative return stroke and then to return to a horizontal position ready for the next operative stroke. At the next severing operation, a tubular bag complete with bottom seam will be detached and fall into a container 69. Jaws 20, 21, anvil 52 and knife 49 may be liquid-cooled to promote rapid cooling of the polyethylene. Instead of a burner, a hot gas nozzle may be used. A plurality of lengths of tubing may be dealt with side by side in the machine. An alternative, hand-operated apparatus comprises a pair of clamping jaws, a pivoted cutting knife, and an anvil which can be engaged by the knife blade and carried away from the sheets during the cutting stroke but after the cutting proper; alternatively a short extra forward.feed of the stock may be effected after the cutting operation. Closing and opening of the clamping jaws may be effected automatically by movement of the knife. A burner or hot gas nozzle may be movable by hand along a rail alongside the bite of the jaws.
